More Boiler Progress (cont)

Here are some pic of the latest progress. Here is a shot of the boiler sitting in the hearth after having the bottom tube plate soldered to the shell. The two lower bushings have been soldered in as well. The whole assembly was upside down for this operation and you can see how gravity assisted the distribution of extra silver solder. Better too much than not enough I suppose....

Here is a shot from underneath - nice fillet all the way around so good joints here.

Now we are going to solder the top tube plate on. So liberal with the flux...

...and apply the heat. I use two MAPP gas torches for this. One has a bigger burner than the other so this gets used for general heating and the other one gets used to supply local heat.

Here we are at black heat still. This will go into the pickle and if there are no visible problems it will be hydro tested.
